Comment:
I reviewed the code, doctests pass, documentation and code are mostly
fine. I added a few reviewer commits, please cross-review.
There is only the question on what to do with integral `alpha <= 0`.
Currently, the result is `0` which is certainly correct for sufficiently
large values of the parameter. However, the rest of the asymptotics code
as I remember it does not really assume "sufficiently large values of the
parameter".
I am not really sure which result is appropriate. Several options:
- `0` - valid for sufficiently large values of the parameter. (current
version)
- `O(1)` - correct, but bad for applications.
- raise an error
- add a warning to the documentation
- add a note to the documentation
